Clearly weaker? I do not think this has happened either, as all the top programs are very close in strenght. Not so long ago, Crafty won CCT-1; while Junior, Shredder 3 and Nimzo were playing. I am ready to accept that these three programs are stronger than Crafty, but I think the difference is not big. > >You could as well say that as you don't attend the tournaments yourself you >don't trust the results.

Ok. I religiously believe in tournaments. And you religiously believe in private testing and the SSDF in particular. > >All the arguments you can provide to belittle the value of the SSDF >actually can be used to point out the weaknesses of tournaments results... > All but the secret vs public games. In tournaments, all games are public. It was not my intention to belittle the SSDF, I believe that do a terrific and useful job, only that I do not pay too much attention to their results. > > Christophe José.
